Little Knitter on the Prairie

This morning on the way to school my oldest daughter told me the following joke that she made up.

M: "If April showers bring May flowers, what do May flowers bring?"
Me: ?
M: "Pilgrims!"
Me: ??
M: "Get it? Like the Mayflower?"

I thought it was cute. Of course knowing kids she very well could have heard it somewhere else but I still thought it was funny.
